Trust
Kept close
The best part of a conversation is often small. A sentence that clicks. A plan you want to keep. A note you want to come back to.
Truffle Journal is built to hold those things with care.
How Truffle Journal works
When something in a chat is worth keeping, you ask ChatGPT to save it to Truffle Journal.
The connected ChatGPT app can save entries, list your entries, and search your journal only when you ask it to. It is there to help you keep and retrieve what matters — not to act on its own.
Connection and permission
Truffle Journal connects to ChatGPT through OAuth.
Today, the smoothest experience is with ChatGPT, where Truffle Journal works as a connected app through MCP. During beta, the iOS app is delivered through TestFlight, and the ChatGPT side is added through Developer mode.
How your data is protected
Your journal is stored in a managed Postgres database.
Data is encrypted in transit with TLS and at rest with AES-256. Access is enforced at the database layer so each user can read and write only their own entries.
What stays true to the moment
You can edit your comments and tags later.
Right now, the saved AI excerpt is kept as a faithful snapshot of what the model said when you chose to save it. We like that boundary. It keeps the saved moment closer to what actually happened.
Sharing
Sharing is something you choose.
Entries can be shared as plain text or as a clean image card.

Still in beta
Truffle Journal is still evolving. As the product becomes simpler and more polished, this page should stay clear about what changes — especially around storage, access, and sharing.
Questions
If something about privacy or security feels unclear, we would rather explain it plainly than hide it behind fine print.
